Question motor bogging down on hard acceleration?

I have a 1994 jeep yj that came with a 2.5 that was blown. I replaced it with a 1989 Chevy 350 TBI, np 205, and turbo 350. I Also Installed a painless wiring system. Upon normal or light acceleration it works fine, If I punch it bogs down. When it is idling it seems to run rich. Timing was adjusted and senors all replaced. Since I am unfamiliar with the TBI system my question is The TBI takes 11-15PSI and I believe the jeeps fuel pump is putting out 30-35psi. Will this cause these issues and will an in line fuel regulator fix the problem?
thank you so much for your response and help.
